New Weapon Idea: Rocket Ship

Greetings! So I had a dream last night about shellshock and thought up a new weapon, called Rocket Ship!

This Weapon has 2 Levels, Rocket Ship -> Space Shuttle

How Rocket Ship Works: The Rocket Ship is like the Hover-Ball, as in it is harder to aim, but the rocket ship goes higher than what your normal shot intended, even breaking the 100 power limit if necessary, and when it lands, it makes 3 explosions like a area strike that do about 30 damage each.

How Space Shuttle Works: Space Shuttle is the obvious upgrade to rocket ship, taking quite a large amount of xp, but basically, the Space Shuttle goes even higher, and splits apart like a real space shuttle, but right before it starts falling down, it splits into 4 pieces which do 25 damage each, obviously the pieces are pretty grouped together since they don't split out until after half of the shot is already made.
